Expression Of Ps2 In Prostate Cancer Correlates With Grade And Chromogranin A Expression But Not With Stage, Hammad Ather, Farhat Abbas, Nuzhat Faruqui, M Israr, Shahid Pervez
Background: The biological potential of prostate cancer is extremely variable. Particular interest is focused on markers not expressed in normal prostatic tissues. pS2 protein expression has been demonstrated in a range of malignant tissues in an oestrogen-independent pathway. Recently, it has been demonstrated that pS2, in prostate cancer, is closely associated with neuro-endocrine differentiation. In the present study, we have analyzed, the potential of Neuro-endocrine and pS2 (TFF1) expression in human prostate cancer determined by immunohistochemistry, in primary adenocarcinoma of the prostate and attempted to correlate this with the clinico-pathologic features of the patient and neuroendocrine expression.
Methods: Ninety-five malignant ...

To investigate the potential functional cooperation between p27Kip1 and p130 in vivo, we generated mice deficient for both p27Kip1 and p130. In p27Kip1−/−;p130−/− mice, the cellularity of the spleens but not the thymi is significantly increased compared with that of their p27Kip1−/− counterparts, affecting the lymphoid, erythroid, and myeloid compartments. In vivo cell proliferation is significantly augmented in the B and T cells, monocytes, macrophages, and erythroid progenitors in the spleens of p27Kip1−/−; p130−/− animals. Immunoprecipitation and immunodepletion studies indicate that p130 can compensate for the absence of p27Kip1 in binding to and ...

Prostate cancer is an enigmatic disease. Although prostatic-intraepithelial neoplasia appears as early as the third decade and as many as 80% of 80 year old men have epithelial cells in their prostate that fit the morphological criteria for cancer, only about 10% of men will ever have the clinical disease and less than 3% will die from it. There have been no significant proven interventions which have altered the natural history of the disease since hormone down regulation was introduced in the 1940s and new research has been poorly supported. There is however an urgent need to develop new criteria ...
Efficient Immortalization Of Luminal Epithelial Cells From Human Mammary Gland By Introduction Of Simian Virus 40 Large Tumor Antigen With A Recombinant Retrovirus, Bartek J, Bartkova J, Kyprianou N, El-Nasir Lalani, Staskova Z, Shearer M, Chang S, Taylor Papadimitriou J
El Nasir Lalani
When defined in terms of markers for normal cell lineages, most invasive breast cancer cells correspond to the phenotype of the common luminal epithelial cell found in the terminal ductal lobular units. Luminal epithelial cells cultured from milk, which have limited proliferative potential, have now been immortalized by introducing the gene encoding simian virus 40 large tumor (T) antigen. Infection with a recombinant retrovirus proved to be 50-100 times more efficient than calcium phosphate transfection, and of the 17 cell lines isolated, only 5 passed through a crisis period as characterized by cessation of growth. When characterized by immunohistochemical staining ...

Seton Hall University Dissertations and Theses (ETDs)
Over the past two decades, advances in RNA structural biology have improved our understanding of the structures and folding properties of naturally occurring RNAs. RNA sequences and structures participate in many specific biological functions, such as those performed by messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), micro RNA (miRNA), short-interfering RNA (siRNA), small nuclear RNA (snRNA) and many others. The noncoding RNAs, such as siRNA, do not express proteins but have been utilized in a wide range of applications, including RNA interference (RNAi) and the regulation of mRNA expression. These important biological functions have been implemented in gene ...

Case Study Of Persons With Cancer Participating In A Community-Based Exercise Program: An Exploration Of Meaning And Change, Barbara K. Haas, Melinda Hermanns, Christina Melin-Johansson
The Qualitative Report
Increasingly, research supports the importance of incorporating exercise into the cancer care paradigm. While quantitative studies have substantiated the significant effects of exercise on physical functioning, the individual’s perspective of participating in an exercise program has rarely been considered. The purpose of this study was to explain the impact of a community based exercise program on the lives of persons with cancer and their caregivers. Based on Bandura’s Social Cognitive Theory, a single explanatory case study with multiple embedded units of analyses was conducted. Interviews were conducted with 10 individuals representing participants with cancer, their caregivers, and health ...

Tolerability Of Induction Chemotherapy Dosing Practices In Acute Myeloid Leukemia Patients, Kaylene M. Peric, David J. Reeves
For patients with high body surface areas (BSA), differing chemotherapy dosing strategies have been utilized in attempts to reduce toxicity. In a retrospective evaluation, we compared the effects of chemotherapy dosing in acute myeloid leukemia patients with high BSA (>2 m2) who received capped doses (n = 12) to those who received uncapped doses (n = 24), and to patients with BSA ≤ 2 m2 (n = 42). There were no statistically significant differences among groups (BSA ≤ 2 m2, BSA > 2 m2 capped, and BSA > 2 m2 uncapped) in the incidences of febrile neutropenia (85.7, 66.7, and ...

A Phase I Dose-Escalation Study Of The Braf Inhibitor Vemurafenib In Combination With The Mtor Inhibitor Everolimus In Subjects With Advanced Cancer, Javier Munoz
UT GSBS Dissertations and Theses (Open Access)
Vemurafenib has been approved in the United States for the treatment of relapsed or refractory BRAF mutation positive malignant melanoma and is being investigated in various other malignancies. The RAS/RAF/MEK/ERK (MAPK) pathway is critical to cell proliferation in many human cancers. The mTOR inhibitors are well known to exert profound anticancer effects across malignancies through inhibition of the PTEN/PI3K/AKT/mTOR (mTOR) pathway. We hypothesize that the toxicity profile of the combination of vemurafenib and everolimus will be well tolerated. The primary objective is to find the maximum tolerated dose (MTD) and the toxicity of the ...
Epigenetic Modulation In Braf Mutated Metastatic Colorectal Cancer, 2016 The University of Texas Graduate School of Biomedical Sciences at Houston
Epigenetic Modulation In Braf Mutated Metastatic Colorectal Cancer, Van Morris
UT GSBS Dissertations and Theses (Open Access)
Introduction: BRAF V600E mutations are associated with poor clinical outcomes for patients with metastatic colorectal cancer (mCRC). Unlike other tumors with the same mutation, BRAF inhibitors are ineffective as monotherapy. CRC tumors with BRAF V600E mutations are associated with global hypermethylation, which may turn off tumor suppressor gene expression. We studied demethylation in BRAF V600E mCRC to restore sensitivity to BRAF inhibitors.
Methods: Tumor databanks were investigated for genes differentially expressed according to BRAF mutation status to identify genes which may be particularly susceptible to epigenetic influence. Mouse xenograft models of BRAFV600E mCRC were treated with vemurafenib or azacitidine, alone ...

Case Report: Pthrp Related Hypercalcemia In Diffuse Large B-Cell Lymphoma, 2016 Thomas Jefferson University Hospital
Case Report: Pthrp Related Hypercalcemia In Diffuse Large B-Cell Lymphoma, Ankita Mehta, Md, Evan Caruso, Md
The Medicine Forum
Hypercalcemia is commonly associated with solid tumor malignancies, but less often with hematologic malignancies. When present in hematologic malignancies, hypercalcemia is often secondary to overproduction of Vitamin D from the tumor cells. Very few cases with parathyroid hormone related peptide (PTHrP) induced hypercalcemia in B-cell lymphomas have been reported. Here we present a 44 year old male with a history of chronic lymphoctic leukemia who presented with hypercalcemia and an elevated PTHrP, found to have a transformation to Diffuse Large B-cell Lymphoma (DLBCL).

The Medicine Forum
Melanoma is the most common tumor to metastasize to the gastrointestinal (GI) tract. 60% of patients who die with malignant melanoma have GI involvement at autopsy1. Symptomatic disease presenting during life is unusual. Anorectal melanoma, a rare tumor that represents 1% of all melanomas and less than 4% of all anal malignancies, manifests with a range of non-specific symptoms and physical exam findings2. In fact, about one-third of lesions may be amelanotic3,4. Initial misdiagnosis as a benign lesion such as hemorrhoid is common.
We report 3 cases of anorectal melanoma presenting as primary GI complaints all without known ...
